BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to computer databases.

2. Related Art

Advancements in digital image processing methods have enabled these technologies to become valuable tools for a host of applications. These include, but are not limited to, documenting work products in such fields as biochemistry, cell biology, pathology, genetics, forensics, geology, metallurgy, inspections of electron devices, quality control applications, material failure analysis, and the like. Digital image processing methods enable pictorial data to be manipulated in ways that enhance the means by which humans can interpret this data. Digital image processing methods typically use computer-processed algorithms or user-operated computer graphics tools. With digital image processing, a picture is not only “worth a thousand words,” but also a source of a substantial amount of data about the subject(s) and the background in the digital image. In general, what is needed is a computer database management system for managing data associated with documents stored in an electronic form. Preferably, such a computer database management system would also be configured to support performing queries or data mining of relevant data at a high rate.

SUMMARY OF THE INVENTION

The present invention can use computer processed algorithms, user-operated computer graphics tools, or both to have data derived from or assigned to the document or the file. The data can be, but is not necessarily, metadata. Computer processed algorithms and user-operated computer graphics tools can be thought of as representing opposite ends of a spectrum of methods by which data can be derived from or assigned to a document or a file. At one end of the spectrum, the derivation or assignment of data is performed automatically. At the other end of the spectrum, a user manually derives or assigns data.

In the present invention, first data is derived from the document, second data is assigned to the document, or both.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Overview

The present invention comprises a method, system, and computer program product for managing data associated with a document stored in an electronic form. If the document is an image, then management of the data is also known as image informatics. Among other attributes, the data can describe complex features found in an image. The document can be a part of a file. The present invention can use computer processed algorithms, user-operated computer graphics tools, or both to have data derived from or assigned to a document or a file.

Computer processed algorithms and user-operated computer graphics tools can be thought of as representing opposite ends of a spectrum of methods by which data can be derived from or assigned to a document or a file. At one end of the spectrum, the derivation or assignment of data is performed automatically. At the other end of the spectrum, a user manually derives or assigns data. More typically, data are derived or assigned by a combination of automatic and manual processes. For example, usually, a user initiates computer processed algorithms to derive or to assign data automatically, or is assisted by user-operated computer graphics tools to derive or to assign data manually. As the arts of deriving data from and assigning data to documents and files progress, data that are currently derived or assigned by mostly manual methods may later be derived or assigned by predominantly automatic processes. Accordingly, the present invention is not limited to current state of the art computer processed algorithms and user-operated computer graphics tools, but is also applicable to future developments in these technologies.

Examples of data that can currently be derived from or assigned to a document or a file with computer processed algorithms include signatures, thumbnails, and other image related attributes; file signatures and other file related attributes; grain sizing and other material analyses; edge detection and analysis; image feature counting and analysis; histograms; and line profiles. Computer processed algorithms can be based upon, but are not limited to, digital image processing methods such as background subtraction, thresholding, smoothing, adaptive filtering, edge enhancements, contrast enhancements, and histogram equalizations. Such methods are known to those of skill in the art.

Examples of data that can currently be derived from or assigned to a document or a file with user-operated computer graphics tools include measurements (e.g., distances, angles, etc.) made by a user of portions of subject(s) in an image, textual annotations made by a user and assigned to the document or the file via an overlay, Boolean values (e.g., true or false) assigned by the user, an identity of the document or the file, a time at which the document or the file was produced, and a name of an individual associated with the document or the file. Some of these can be obtained with the assistance of overlay templates. User-operated computer graphics tools can be based upon, but are not limited to, character user interfaces (e.g., keyboards) and graphical user interfaces.

Generally, a graphical user interface is a system comprising hardware, software, firmware, or any combination thereof that allows a user to interface with a computer via its display system. Characteristics of a graphical user interface can include, but are not limited to, a bit-mapped display, an Ethernet® network for transferring data and commands, an optical cursor control device (e.g., mouse, trackball, stylus, touch pad, touch screen, or the like), windowed display of operations, icon-initiated programs, and menus for programming options. Apple® Macintosh® and Microsoft® Windows™, for example, are applications of graphical user interfaces that can provide a basis for a graphical user interface of the present invention. The present invention is not limited to these examples, but is applicable to other existing and future-developed graphical user interfaces.

The data derived from or assigned to a document or a file can include metadata. Metadata are data about the document or the file that can be used to identify it in an index. Such metadata can include, but are not limited to, some of the data defined by the Dublin Core Metadata Initiative® hosted by OCLC Research of Dublin, Ohio, U.S.A. The technical standards of the Dublin Core Metadata Initiative® are incorporated herein in their entirety by reference.

The computer processed algorithms and user-operated computer graphics tools used to derive data from or assign data to documents or files are incorporated in, for example, the Image-Pro® and IQstudio™ families of products offered by Media Cybernetics Inc. of Silver Spring, Md., U.S.A.

In an application, the present invention provides a database that allows a user to capture, store, and organize image related data in real time as the user is looking at or analyzing images. Later, the data can be queried, archived more permanently, analyzed further using data mining tools, or any combination of the foregoing. Data irrelevant to a particular analysis can be stored in a separate database and indexed to the database of the present invention so that queries or data mining of relevant data in the database of the present invention can be performed at a high rate. Because the database of the present invention can index data from different databases, the database of the present invention can automatically update its schema (the data structure information) as needed as data is accessed from different databases.

Preferably, the database of the present invention is an object oriented database. An object oriented database organizes related data as elements in a set. The set is known as an object and is defined by a type. The elements are known as attributes. A first object can be an attribute of a second object. The first object is known as a child object and the second object is known as a parent object. The FastObjects™ family of products, offered by Poet GmbH of Karlsruhe, Germany, is an example of object oriented databases in which the present invention can be implemented. However, the skilled artisan recognizes other database architectures by which the present invention can be implemented. Accordingly, the present invention is not limited to an object oriented architecture.

For convenience, the present invention is described in the context of images of results of DNA genotyping experiments as displayed in microarrays. However, it should be understood that the present invention can be adapted for use in many other applications including, but not limited to, work products in such fields as biochemistry, cell biology, pathology, genetics, forensics, geology, metallurgy, inspections of devices with feature sizes substantially at or less than a micron, quality control applications, and material failure analysis. Furthermore, the present invention can be used to manage data associated with documents of all types and is not limited to managing data associated with images.

FIG. 1 illustrates an exemplary image in which associated data are managed in an embodiment of the present invention. An image 100 shows a sample of results of a first DNA genotyping experiment as displayed in a microarray. The microarray has, for example, four result sites: A1 102 a, A2 102 b, B1 102 c, and B2 102 d. Image 100 can be, but is not necessarily, a part of a file 104.

FIG. 2 illustrates exemplary data derived from and assigned to the image. Data derived from image 100 are defined, for example, by the following attributes (and associated data types): an image size 202 (e.g., number of bytes) of image 100, a height 204 (e.g., number of pixels) of image 100, a width 206 (e.g., number of pixels) of image 100, an area 208 a, 208 b, 208 c, and 208 d (e.g., number of pixels) of each of the four result sites, and an intensity 210 a, 210 b, 210 c, and 210 d of each the four result sites (e.g., average of values stored in the pixels that define the area of a result site). Data assigned to image 100 are defined, for example, by the following attributes (and associated types): an identity 212 (e.g., series of ASCII characters) of the first DNA genotyping experiment and a name 214 (e.g., series of ASCII characters) of an individual who conducted the first DNA genotyping experiment. If image 100 was captured (at any time), then the data assigned to image 100 can include a time 216 (e.g., series of ASCII characters) at which image 100 was captured. If image 100 is a part of file 104, then the data assigned to image 100 can include data derived from or assigned to file 104. Data derived from or assigned to file 104 can be defined, for example, by the following attribute (and associated data type): a file size 218 (e.g., number of bytes) of file 104.

FIG. 3 illustrates an exemplary object, in a database, in which data derived from and assigned to the image are organized. In a database of the present invention 300, identity 212, for example, defines an object 302. The remaining data are attributes of object 302. For example, each of image size 202; height 204; width 206; areas 208 a, 208 b, 208 c, and 208 d; intensities 210 a, 210 b, 210 c, and 210 d; and name 214 is an attribute of object 302. Optionally, object 302 can include image 100 (or a reproduction of image 100) as an attribute. If data assigned to image 100 includes time 216, then object 302 can include an attribute for time 216. If image 100 is a part of file 104, then object 302 can include an attribute for file size 218, an attribute for a memory location 304 (e.g., address) at which file 104 is stored, or both.

FIG. 4 illustrates an alternative organization of the object. Data related to each of result sites A1 102 a, A2 102 b, B1 102 c, and B2 102 d can be organized as a child object of object 302. For example, attributes for area 208 a and intensity 210 a can be organized as child object 402 a, attributes for area 208 b and intensity 210 b can be organized as child object 402 b, attributes for area 208 c and intensity 210 c can be organized as child object 402 c, and attributes for area 208 d and intensity 210 d can be organized as child object 402 d.

So that queries and data mining of relevant data in object 302 can be performed at a high rate, the present invention allows data irrelevant to a particular analysis to be stored in a separate database and indexed to database of the present invention 300. For example, a user may desire to perform queries or data mining of data related to result sites A1 102 a, A2 102 b, B1 102 c, and B2 102 d, but consider the remaining data of object 302 irrelevant to a particular analysis. In this case, the remaining data of object 302 can be stored in a separate database and indexed to database of the present invention 300 so that queries and data mining of data related to result sites A1 102 a, A2 102 b, B1 102 c, and B2 102 d can be performed at a high rate.

FIG. 5 illustrates an exemplary relationship between databases. This example relationship includes database of the present invention 300 and a second database 502. In database of the present invention 300, an object 504 is defined by identity 212. Object 504 includes child objects 402 a, 402 b, 402 c, and 402 d from object 302. In second database 502, an object 506 is also defined by identity 212. Object 506 includes the remaining attributes from object 302. In database of the present invention 300, object 504 also includes an attribute for a memory location 508 (e.g., address) at which object 506 is stored. With this relationship, a user can perform queries or data mining data related to result sites A1 102 a, A2 102 b, B1 102 c, and B2 102 d at a high rate. Furthermore, access to the remaining data related to image 100 is maintained via object 506 so that queries and data mining can also be performed for this data.

Because database of the present invention 300 can index data from different databases, database of the present invention 300 can automatically update its schema (the data structure information) as needed as data is accessed from different databases.

FIG. 6 illustrates another exemplary relationship among databases. This example relationship includes database of the present invention 300, a third database 602, and a fourth database 604. Third database 602 includes object 302 for data related to the first DNA genotyping experiment as these data were originally derived or assigned. Fourth database 604 includes an object 606 for data related to a second DNA genotyping experiment as these data were originally derived or assigned. The data of the second DNA genotyping experiment is organized in object 606 in a manner that corresponds to the organization of the data in object 302. However, rather than having an attribute for name 214 of an individual who conducted the second DNA genotyping experiment, object 606 has an attribute for an overlay of textual annotations 608 (e.g., series of ASCII characters).

Database of the present invention 300 includes a first object 610 and a second object 612. First object 610 corresponds to object 302 and second object 612 corresponds to object 606. First object 610 includes an attribute for a memory location 614 (e.g., address) at which object 302 is stored and an attribute for an overlay of textual annotations 616 (e.g., series of ASCII characters). Second object 612 includes an attribute for a memory location 618 (e.g., address) at which object 606 is stored and an attribute for a name 620 (e.g., series of ASCII characters). With this relationship, a user can access corresponding sets of data for the first DNA genotyping experiment and the second DNA genotyping experiment even though the sets of data that were originally derived or assigned for the first DNA genotyping experiment and the second DNA genotyping experiment are not corresponding. Advantageously, the data related to each of the DNA genotyping experiments are maintained in the corresponding databases as these data were originally derived or assigned.

FIG. 7 illustrates exemplary query objects. In this example, database of the present invention 300 includes object 302, object 606, a third object 702, a fourth object 704, and a fifth object 706. Third object 702 is a query object. Third object 702 is, for example, defined as the results of querying object 302 and object 606 for data related to result site A1 102 a for the first DNA genotyping experiment and the second DNA genotyping experiment. Third object 702 includes an attribute for a memory location 708 (e.g., address) at which subset 402 a for the first DNA genotyping experiment is stored and an attribute for a memory location 710 (e.g., address) at which subset 402 a for the second DNA genotyping experiment is stored. Fourth object 704 is also a query object. Fourth object 704 is, for example, defined as the results of querying object 302 and object 606 for data related to result site A2 102 b for the first DNA genotyping experiment and the second DNA genotyping experiment. Fourth object 704 includes an attribute for a memory location (e.g., address) at which subset 402 b for the first DNA genotyping experiment is stored and an attribute for a memory location (e.g., address) at which subset 402 b for the second DNA genotyping experiment is stored. Third object 702 and fourth object 704 can be child objects of fifth object 706. Fifth object 706 is defined as the results of querying object 302 and object 606 for data related to result site Al 102 a and result site A2 102 b for the first DNA genotyping experiment and the second DNA genotyping experiment.
